CHX2191
RoHS COMPLIANT
21-42GHz Frequency Multiplier
GaAs Monolithic Microwave IC
Description
The CHX2191 is a frequency doubler
monolithic circuit.
It is designed for a wide range of
applications, from military to commercial
communication systems. The backside of
the chip is both RF and DC grounded.
This helps to simplify the assembly
process.

The circuit is manufactured with a pHEMT
process, 0.25µm gate length, via holes
through the substrate, air bridges and
electron beam gate lithography.
